TYPOG RAPH.

SPECIFICATION forming part of LettersPatent No. 520,238, dated May22,1894.

Application filed January 13,1892. Serial No. 417,938. (No model.)

To aZZ whom it may concern.-

Be it known that I, HOSEA W. LIBBEY, a citizen of the United States,residing at Boston, in the county of Suffolk and State of Massachusetts,have invented certain new and useful Improvements in Typographs, ofwhich the following, taken in connection with the accompanying drawings,is a specification.

The object of my invention is to produce a typograph or apparatuswhereby a line of type can be set and then brought into contact with thesurface of a suitably prepared paper so as to form a matrix.

Theinvention consists in certain details of construction of a frameandaseries of wheels or disks having upon their peripheries letters orcharacters and mechanism for operating them, the said wheels or disksbeing so mounted that they can be readily turned by the operator, andlocked when in the desired position, and after the line is completed thewhole series of wheels or disks is brought into a proper position to bebrought down and make an imprint upon a strip of impressionable paperthat is to form the matrix, line after line being thus impressed uponthe paper until a full page or column has been impressed when thepaperis cut off and is ready to receive the metal to form theelectrotype for printing.

The invention also consists in certain other details of construction ashereinafter fully described and pointed out in the claims.

Referring to the accompanying drawings:

, Figure lrepresents a side view of an apparatus embodying my invention.-Fig. 2- is a front elevation of the same. Fig. 3- is a longitudinalsection through the type wheels or disks, and the upper portion of theapparatus. Fig. 4- is alongitudinal'section taken on the line 00, a, ofFig. 1. Fig. 5- is a side view of one of the type wheels or disks. Fig.6- is an edge view of a portion of one of the type wheels or disks. Fig.7- is a similar view showing the capital letters half on one wheel ordisk, and the other half on the next adjacent wheel or disk. Fig. 8 is aside view of the locking pin.

A, A, represent the side frames of the apparatus secured together bybolts a, a, and at their upper ends by cross bars I), the upper straightportions of these side frames are formed with a groove in which asliding plate lugs a, formed upon the frames A, the sliding plates areeach formed with an extension B, which at its lower end is connected toa treadle bar D, fulcrumed on a bar or bolt 6, secured to rear legs ofthe side frames A, the forward end of this treadle bar is formed with afoot rest 01, so that'when the foot of the operator is placed upon therest d, and forced down, it carries with it the side plates B. A stop 61is secured upon the front bar a, so that when the treadle D, isdepressed it will always be brought to the same point.

E, E, are a series of wheels or disks, preferably of brass, and havingupon their peripheries, in duplicate, letters or characters representingthe entire alphabet both capitals and small letters as well as stops andother signs used in printing, that is to say, one set of letters andsigns are on one side of the said disks, and corresponding letters orsigns diametrically opposite, so that when one line of reading matter isset by the operator near the upper portion of the disks, which would beat about an angle of fortyfive degrees from the center the correspondingletters or signs will be immediately opposite so that by turning thedisks a slight distance say one-eighth of adiameter from him so as tobring the line that has been set perpendicularly over the center of thewheel the corresponding letters will be brought to the center of themachine so that when the treadle D, is depressed, the dies or disks willbe brought down and come into contact with a strip of paper F, that iscaused to travel over a table or bed plate G. I

The characters are not assembled at the printing point in the firstplace for the reason that they can be more readily seen before the disksare turned to bring the characters to such point.

The paper F, is wound upon a roller H, the spindle of which runs inbearings a cast in one with or secured to the front portion of the sideframes A. This paper passes overa loose roller 1, carried in bearings (1also formed in one with or secured to the front portion of the frames A.The paper is fed along automatically in any convenient manner. In thedrawingsI have'shown four feed Wheelsg, mounted upon the shafts h,carried by brackets 2', secured to the under side of the table G; oneach end of the shafts h is secured a pawl wheel j, those at the rearportion of the machine being operated by a pawl J, secured to thesliding plates B,-so that when the plates B, are drawn down the pawlswill not'operate the ratchet wheels but when the sliding plates B, areby the springs O, returned to their normal position then the pawls willcome into contact with the teeth of the rear ratchet wheels and causethem to be rotated suflicient to move the paper F, the required distancebetween one line and another. The front and rear shafts h, are caused tooperate simultaneously by a belt or chain K, passing around a pulley orsprocket wheel is, secured on each of the shafts h; as thus describedthe front feed wheels j, are only operated when the rear ones areactuated by the pawls J, on the sliding plates B, but sometimes it isrequired to leave more than one ordinary space between the lines, toaccomplish this I secure to the front frame of the machine a pawl leverL, which is free to be actuated by the operator; thus by the movement ofthe pawl lever L, the paper F, may be fed forward without receiving animprint from the type disks 01' wheels E.

The type wheels or disks E, are recessed out between each letter orcharacter as will be best seen in Fig. 5, in which the surfaces 1, eachbear a letter or character, and 2 are recesses between such letter orcharacter. In the surfaces immediately under each of the recesses 2, isformed a recess 3, preferably of triangular form as shown into which alooking bar 4:, is pushed by the operator as he sets the wheels E, inposition. A curved slot is cut in the left hand side plate B, as shownin dotted lines in Fig. 1, so that after the plates have been lockedtogether they can be moved the required distance as above described. Asthe type wheels are set in place the locking bar is pushed through themuntil all of the plates are in place and the locking bar extends throughall of them, then by the knob on the end of said bar the plates areshifted or rotated about one-eighth of a circle, and the end of thelocking bar is then pushed through a hole q, in the right hand slidingplate B. I prefer to form a groove in the inner side of this plateshownin dotted lines at q in Fig. 1-so that when the locking bar has beenpushed through all of the type wheels it will enter the said groove andthe wheels can then be turned until the pin strikes the end of thegroove when it will be in place to be pushed through the hole in saidplate, and hold the plates in the proper position to be brought downupon the prepared paper.

In order to facilitate the removal from and replacing one set of wheelsfor another set of a different style of type, I mount them upon a tubeM, having an enlargement m, at one end and a nut 01, at the other end;this tube is of a length just sufiicient to fit between plates 13; thetype plates E, are first mounted upon said tube M, and secured by thenut n, then lowered into position and around bar or spindle P, insertedthrough said tube and the side plates 13. One end of this bar is pro-Vided with a handle 19, and a collar p, to form a stop, and the otherend is formed with a screw upon which is a nut 19 which when screwed uptight holds the said bar rigid between the two plates B, B.

The type wheels may be made of a thickness sufficient to receive thesmall and capital letters, or of such a thickness as to receive only thesmall letters in which case half of the capital letters would be uponone wheel and the other half on the wheel next adjacent in which casewhen a small letter is required only one wheel would have to be set butwhen a capital letter is required a wheel bearing half of said letterwould be set and then the next adjacent wheel turned so that thecorresponding half of said letter will be brought opposite to theportion of the wheel already set.

It will be seen that the wheels as they are adjusted are locked by thelocking bar 4, and after the line is complete they are turned so as tobring the corresponding line on the under side of the disks immediatelyin the center of the machine; then the treadle D, is depressed so as tobring the type wheels or disks into contact with the paper and formal:im-" print therein, and by the travel of the treadle being regulated bythe stop (1 all imprints made in the paper will be of a uniform depth.After the imprint of one line has been made the locking bar 4 iswithdrawn thus unlocking the wheels which are then free or loose uponthe spindle P, and are free to be turned round either way upon saidspindle by the operator as may be required to form another line.

What I claim is 1. In a typograph, the combination, with a frame, of apair of vertically movable plates therein, the lower ends of the platesbeing extended and provided with a treadle and one of the plates beingprovided with a curved slot terminating in a hole at one end, a seriesof type wheels journaled between the plates, provided with registeringnotches, and a lock ing bar for engaging with the notches, said barhaving one end adapted to move in the slot and enter the hole,substantially as set forth.

2. In a typograph, the combination, witha frame provided with lugs, twomovable plates within the frame, each plate being provided withextensions to register with the lugs of the frame, a spring between eachextension and its lug, a series of type wheels journaled between theplates, means for locking said wheels against rotation, a plate belowthe wheels for the reception of a sheet of impressible material, andmeans for moving the wheels toward the plate, substantially as setforth.

3. In a typograph, the combination, of a frame, movable plates thereinprovided with type wheels, a table below the wheels, shafts journaledbelow the table, eachof which is provided with feed wheels and a ratchetwheel for rotating it, a pawl on the frame for engaging with one of theratchet wheels, and a lever for engaging with the other ratchet wheel,and means for causing said shafts to turn in unison, substantially asset forth.

4. In atypograph, a series of wheels or disks having letters orcharacters upon their peripheries and integral therewith said wheels ordisks being mounted upon ashaft carried by sliding plates that .arebrought down when an imprint is to be made in combination with a stripof impressible paper, feed wheels arranged on shafts at each end of thebed plate, ratchet wheels on the ends of one of said shafts and pawls onthe sliding plates for imparting a rotary motion to the feed wheelswhereby the paper is automatically fed for ward as the disks are beingraised after the type wheels have been brought into contact with thepaper substantially as set forth.

5. In atypograph,wheels or disks each having a series of letters andcharacters upon one half of its periphery and a corresponding series ofletters and characters upon the other half the two corresponding lettersbeing diametrically opposite each other said wheels or disks havingopenings between each pair of characters but in the rear of said lettersor characters in combination with a locking bar adapted to fit into saidopenings and hold the wheels as they are adjusted, substantially as setforth.

6. In a typograph a series of wheels each having on its periphery a fullalphabet of small letters, figures and signs and half sections of acapital alphabet so arranged that when two adjacent disks are properlyadjusted they will form a complete'alphabet of capital letterssubstantially as set forth.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, on this 23d day of December, A.D. 1891.
